Supreme Ontario Deck and Fence builds custom decks, fences, pergolas, and patio covers for Ontario homeowners. We have been serving this city since 2016, and we know exactly what the local climate, soil, and permit process require.

Ontario yards come in a lot of shapes and sizes - from narrow lots near downtown to larger backyards in the newer subdivisions on the east side. A custom deck design and build starts with your actual yard, your actual budget, and how you plan to use the space - not a template from a catalog.
Ontario summers regularly push past 100 degrees, and that heat, combined with clay soil movement through the wet and dry seasons, puts real stress on existing decks. Boards crack, posts shift, and railings loosen - problems that only get worse if you wait.
Composite decking holds up better than wood under Ontario's intense UV exposure and triple-digit summer temperatures. The boards do not fade, splinter, or absorb moisture the way natural wood does - which makes them a popular choice for families who want a low-maintenance outdoor space.
Ontario's fall Santa Ana winds regularly gust past 60 mph and have a way of revealing which fences were installed properly and which were not. Vinyl fencing stands up better to those gusts than wood, does not rot or splinter, and requires almost no upkeep through the seasons.
A pergola turns a hot Ontario backyard into a usable outdoor space through even the harshest summer afternoons. With the right placement and optional shade cloth or louvered panels, a pergola can cut direct sun exposure dramatically and extend the hours your family actually spends outside.
Pools are common in Ontario, and the deck around a pool takes more punishment than almost any other outdoor surface. Slip resistance, heat retention, and materials that can handle years of wet-dry cycling without cracking all matter here - especially on properties that get full southern sun exposure.
Ontario sits in the Inland Empire, and the climate here is genuinely hard on outdoor structures. Summer temperatures regularly exceed 100 degrees, with intense UV exposure that fades and dries out wood finishes, caulking, and paint faster than in coastal Southern California. That same heat bakes clay soils into a hard crust during dry months, and then those soils swell when winter rains arrive. The repeated expansion and contraction is one of the main reasons deck posts drift, concrete cracks, and fences lean in this part of the state.
The housing stock adds another layer. Ontario has a wide range of home ages - Craftsman bungalows near Euclid Avenue that were built a century ago sit alongside 1970s ranch homes and newer stucco subdivisions from the 1990s and 2000s. Each era of construction has its own quirks. Older homes near downtown often have original concrete flatwork or legacy fence posts that need to come out before new work can go in. Newer tract homes in the southern part of the city sometimes have HOA rules that govern deck materials, fence heights, and color choices. A deck builder who has actually worked across all of Ontario knows which neighborhoods need what, and how to handle the permit and HOA processes that come with them.
Our crew works throughout Ontario regularly, and we pull permits directly with the City of Ontario Building and Safety Division for every project that requires one. We know what the local plan checker typically asks for on deck and fence submittals, and we build that into our project timelines so there are no surprises for homeowners on their scheduling.
Ontario is a big city, and the neighborhoods feel different depending on where you are. From the tree-lined streets along historic Euclid Avenue to the newer stucco tracts near Ontario Mills off the 10 freeway, we have worked on homes at both ends of that spectrum. The older homes close to downtown tend to have more deferred maintenance and older footings that need to be assessed before any new work goes on top of them. The newer subdivisions closer to the city's east and south edges often involve HOA approval as a first step.
Ontario sits directly next to Montclair to the west and borders Rancho Cucamonga to the north. We serve all three cities regularly, so homeowners near any of those borders can count on the same crew and the same local knowledge.
Reach out by phone or through the contact form and we will respond within one business day. We ask a few quick questions about your project so we can come prepared - no lengthy intake process required.
We visit your property, look at the actual site conditions, and give you a written, itemized estimate at no charge. We will flag any permit requirements at this stage so the cost and timeline are clear before you commit to anything.
We handle permit submittal with the City of Ontario and schedule construction around the review timeline. Most builds take three days to two weeks on-site once materials arrive and permits are approved.
We walk through the finished project with you before we consider it done. For permitted work, we coordinate the city final inspection so the permit is closed properly and your records are clean.
We serve all of Ontario, CA - from the neighborhoods near Euclid Avenue to the newer subdivisions on the east side of the city. Call us or fill out the form and we will get back to you within one business day.
(909) 738-1084Ontario is a city of roughly 185,000 people in San Bernardino County, about 35 miles east of downtown Los Angeles. It sits in the heart of the Inland Empire and has grown steadily over the past several decades, which means its housing stock ranges widely - from Craftsman bungalows on tree-lined streets near the historic Euclid Avenue corridor to mid-century ranch homes from the 1960s and 1970s, and then on to newer two-story stucco subdivisions built in the 1990s and 2000s toward the south and east edges of the city. Ontario is also home to Ontario International Airport, one of the major cargo and passenger airports serving the region, and a large industrial and logistics sector centered around the 10 and 15 freeways.
About half of Ontario's housing units are owner-occupied, with a median home value that reflects steady demand from buyers who want to be close to both Los Angeles and the amenities of the Inland Empire. Homeowners here tend to put real money into their properties. The city's diverse building stock means there is almost no such thing as a one-size-fits-all home improvement project in Ontario - a contractor who has actually worked across the city knows what each era of construction brings with it. Our crew also serves neighboring Upland to the northwest and Pomona to the west, so if you live near any of those borders, you are in our service area.
